Well, not the same way, but udev will interfere in this scenarios: - Uml assigns MAC addresses automatically so MAC address will depend on when the interface was started and whether it was configured before it was started. In any case MAC addresses change when the interface is 'up'ped (from '00:00:00:00:00:00' to something else) or connected to different uml-switches (without changing the UML machine itself). You can staticly assign them, however, See http://edeca.net/articles/bridging/questions.html#macproblems2 - Vmware can be used to run linux already installed in a local hard disk (instead of using a virtual disk). In this case, the MAC address given by Vmware for its bridged network interfaces (sharing the system's network interfaces with the host) will be within Vmware's assigned OID MAC addresses, which is different from the network interface's MAC address when the system boots (without virtualization) and uses the real network interface directly. There might be some other situations in which MAC addresses change (changing an interface from bridged-mode to host-only or so), but are more similar to the device renaming in udev when ethernet cards are removed or replaced. - When you "move around" a Vmware virtual image (to a different host or to a different directory, or clone it) MAC addresses might also change: http://www.vmware.com/support/ws55/doc/ws_net_advanced_mac_address.html and http://kb.vmware.com/KanisaPlatform/Publishing/476/507_f.SAL_Public.html Google for "mac address vmware udev" and you'll find many users having problems with udev in these cases.
